Water Restrictions

Key details: Watering Days: 2 to 3 per week typical. Hours: Before 10 AM / after 6 PM. Xeriscaping: HOAs cannot ban (CRS). Drought: Staged restrictions.

Native Plants

Westminster may encourage or require native and drought-tolerant landscaping. Some areas restrict traditional grass lawns in favor of water-efficient alternatives.

Key details: Xeriscaping: Encouraged or required. HOA: Cannot ban in many states. Rebates: May be available. Invasive Species: Removal may be required.

Varies by jurisdiction. HOA fines for non-compliance may be unenforceable if state law protects xeriscaping rights.

If you are coming from a city with tighter rules, you will find Westminster gives residents more flexibility on native plants.

The Bottom Line

Compared to many U.S. cities, Westminster gives residents more room on landscaping rules. 2 of the 8 rules here are rated permissive. But permissive does not mean unregulated. There are still requirements, and the city does enforce them when violations are reported.
